Two new sterols, columnaristerols B (1
) and C (2
), along with two known analogues, 5,6-epoxylitosterol (3
) and litosterol (4
), were obtained from the octocoral Nephthea columnaris
. The structures of new sterols 1
were elucidated by using spectroscopic methods and comparing the spectroscopic data with those of known related metabolites. Sterol 3
was found to suppress superoxide anion production and elastase secretion by human neutrophils.
